Located in Switzerland, this paragliding site offers a takeoff altitude of 1010 meters with a height difference of 350-470 meters. It is occasionally used and suitable for soaring and cross-country flights. Some pilots also list this site in French databases. Takeoff is oriented from southeast to southwest. It is not advisable to fly with winds exceeding 20 km/h. The best flying conditions are typically from 12:00 to 14:00 during the summer, with flyable conditions from 9:00 am to 5:00 pm if the prevailing wind is not too strong. For current wind conditions, you can check the 'The Dole' (DOL) weather station at 1670 meters: [MeteoSuisse](http://www.meteosuisse.admin.ch/web/fr/meteo/temps_actuel.par0023.allStations.html). Access to the site is via Les Rousses towards La Cure. After crossing the border towards St Cergue, turn left towards Arziet. Take the first right under the forest and then another right. Park the car before the chalet on the left side of the road, not in the parking lot. The journey takes about an hour from Claivaux. The site is known for its excellent thermals, making it a good spot for cross-country flights. The takeoff area is spacious, allowing multiple wings to be laid out simultaneously. However, be cautious of the nearby cliff. For landing, use the large field at the village entrance to the left of the takeoff. Note that the landing area is quite distant from the takeoff, so precision is required. If you descend below the rocky bar in front of the takeoff, head directly to the landing zone and hope for the best. There are no intermediate landing spots between the takeoff and the official landing area. Retrieval can be done by car or the small train.
